PAPER CLIP.

Application led April l, 192.5, Serial No. 19,903, and in Gerniany March 2, 1925.

singly or in bundles.

The invention has for its main object the provision of a paper clip which will secure-A ly hold. bundles or packs oi considerable size and thickness.

Another object of the invention is the ro visionot a paper clip ot most simple an et tective design by winding and bending the ttl spring forming ,the clip repeatedly in dil'-y terent planes, so that the clamping stri s oit the clip, which engage the sheets to be eld, will hold same securely in any position with; out relaxation ot the spring ends by means oi which the plied. i A further object of the Kinvention is to so construct the clip that the applied spring pressure will act evenly all overtlie tull length et the sheets to be held.

According to the invention the paper clip is designed so that the various members of the clip and the suspension member cooperate ediciently to clamp the paper in place .irrespective ot whether thin or vthick dll bundles ot paper are secured thereon.

The clip, apart troni the spring proper9 consists ot a back or outer strip and an inner strip, otwhich the latter is `JEorined so es to eliminate friction andv so as toirnpart yiiicreased strength and security to the spring ends. Besides. the spring is connected to dll dll

dll

the basl.' ot the clip at a neutrel point, and its ellective parts are thus eble to move :treely., while the spring ends elweys taire that Aposition which gives the greatest spring pressure upon sheets to be held Ithe acconapenyiiig drawing illustrates the invention by way ot' erianiple. I lig. l i s a liront elevation et the improved paper clipZ while Fig, t2 is a part sectional eide elevation thereof'.

` Figure 3 `is a vertical sectional view ot the saine showing the situation oil paper held iii pressure on the paper is ap-4 portion d2 of the inner strip d. The sheets of paper to be held are clamped by means of the spring clip a which 1s fastened at its U- shaped neutral or4 dead position h to a T- shaped member z'" which member is secured by eyelets Il: orother suitabl means to the depending edge c oi the baci d. if The said spring clip, according to the drawing,- is

wire to form the ll-shaped central portion and the oppositely extending arms, which arms are united to the U-Sliaped` portion by coils a@ the Vends being torined ot spring coils e and also bent to form integral hooks or loops f and so that the sus ension hooks or loops of which are torine in the wire extend into the tree ends' e which are arranged between the inner strip d and its .t'olded or bent over edge portion d2.. BetweeiiA the said tree ends and the suspension `lornied ot one continuous length of spring` hooks the spring is set od -tovlorin a shoulder it. lt is preferable to provide the inner strip d at its depending top edge with a metallic ledge or` other strengthening ineinber o which also serves to eliminate or reduce the 'friction between these parts.,

The invention evidently is not limited to the enact configuration shown in the drawing but may be niodied to ineet requirements. within lthe Scope ot the following claims.

What li claim is l. A clip of the class describeda compris ing an outer strip and an inner strip, each provided with a bent over edge portion, that nii the inner strip being arranged inthe nent over edge'portion cis the outer .strip and a3 strip to press the folded or' bent over por` tionsoi" said strips together to clamp paper therebetween. i

2. A. clip ot the class described, eoinpris ing an outer strip and an inner strip, each provided with a bent over edge portion, that olZ the inner strip being arrangedin the bent over edge .portion of the outer strip and a springexerting its tension between the inner'strip 'and its bent over edge and also exerting its .tension on the bent over portion ofthe outer strip to press the folded or bent over portions of said strips together to clamp paper therebetween, seid spring 11ol .dit

ela

comprising si .piece of spring wire'attached too the bent over portion of the outer Strip A and having a spring coil bearing on the fol ed portion of the outer strip and a. spring,

l terminal bearing between the inner strip and its folded over edge to press the folded portions of said strips together.

`3. A clip of the class-described, comprising an outer strip and an inner strip, each provided with a. bent over edge portion, that of the inner strip being 'arrnged in the bent over edge portion of the outer strip and a spring exerting its tension between the inner strip and its bent overedge and also exerting its tension on the bent over portion of the outer strip topress the foldedor bent over portions of said strips together to clamp a spring coil bearing paper therebetween, said spring comprising a piece of spring wire attached to the bent over `portion of the outer stri and having' on the olded portion of the outer strip an a spring terminal bearing between the inner strip and its folded over edge to press thefolded portions of said sprlps together and being also bent to form a hook wherewith to suspend the device. 4. A clip ofthe class described, comprising lan outer strip and an inner strip, each' prising a spring wire bent to form a. central portion and oppositely extending arms, said central portion being secured tothe folded over edge portion of thev outer strip and said spring wirebeing formed with coils which beur on said foldedover portion, being also bent to form hooks wherewith to suspend the device andv the free terminal portions'` which bear in the fold of the inner strip. In witness whereof I aiiix my signature.
